OF THOMASVILLE, GEORGIA.

PLOW.

Application filed May 29, 1922. Serial No. 564,391.

To all whom it may concern:

Be it known that I, JAMES W. ll/lon'reonr n a citizen of the United States, reiihomasville, in the county of Thomas and State of Georgia, have invented a new and useful Flow, of which the followiug is a specification.

This invention relates to a plow and it is designed more particularly as an improvement upon thestructure disclosed in Patent No. 1,147,420 issued to me on July 20, 1915.

It is an object of the present invention to pr vide the plow with a runner so constructed that it will not unduly limit the adjustment of the king" bolt used for attaching the plow point to the standard. t is the practice among farmers to gradually adjust their plows along the stocks or standards as the points wear off butinthose plows utilizing runners the adjustment is limited and it becomes necessary to discard'the point before the maximum wear has been obtained. In the present invention, however, the runner so mounted that the bolt which connects the point to the standard or stock can be adjusted downwardly practically to the lower extremity or the stock or standard.

Another object is to provide a runner to which either single or double sweeps or scrapers can be attached and which will hold them at any desired angles to the runner.

With foregoing and other objects in riew which will appear as tne description proceeds, the invention resides in the com bination and arrangement of parts and in the details of construction hereinafter described and claimed, it being undc stood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings,

Figure 1 is a vertical section through the plow point and the stock and showing adjacent parts.

Figure 2 is a plan View of the runner and showing a pair of single scrapers attached thereto.

Figure 3 is a view partly in side elevation and partly in section showing the means cinploycd for attaching a double scraper to the runner.

Figure i is an enlarged section on line Figure 3.

Referring to the figures by characters of reference 1 designates a metal beam to the downwardly curved rear end portion of which are bolted the side portions of a metal stock or standard 2, there being a longitudinal slot 3 formed within thir stock or standard between the lower end of the beam 1 and the lower end of the stock, as shown particularly in Figure 1. This slot is designed to receive the king" bolt i used for fastening the plow point 5 to the stock. This plow point is prefeably formed with a shank 6 having a longitudinal slot 7 through which the bolt i ext-ends, there being a nut 8 on the rear end of the bolt and engaging the stool: whereby the head of the bolt can be ca Hal to bind the shank of the plow against the stock. The plow point can be of any form desired and can, if preferred, be provided with a mold board integral with or separate from the point.

A runner 26 is provided back of the stock or standard .2 and the front end of this runner is forked as shown at 27 so as to straddle the lower end of the stock 2, there be ing a bolt 28 for pivotally attaching this forked end of the runner to the stock. The fork 27 is so proportioned that if desired the bolt 4 and its nut 8 can be adjusted downwardly into the fork in order to hold the plow point at its lowermost position. This will be obvious by referring to Figure l.

The runner 26 is provided, bacl: of the fork with an upstanding portion 2;) having lat parallel side faces and a front face which concared from cud to end and inclined downwardly and forwardly, this front face lzoinp; toothed as shown at 30. An opening 31 is extended transversely through. the runner at a point near the fork and a slot 32, which is concentric with this opening-1', extends transversely through the upwardly projecting portion 29.

A toothed bloc-l; or saddle is placed astride the concaved toothed face 30 of the runner so that the teeth in this saddle can engage the teeth 30. The sides of the sad dle are designed to lap the openings 31 and 32 in the runner. A longitudinal slot 39 is formed in the front of the block and a groove 40 is provided in the toothed face of the block to receive the head ll of a bolt 42 adjustable in the slot 39. This bolt extendsthrough the intermediate portion 43 of the scraper and from which portion extend the rearwardly diverging wings as. Obviously with this arrangement the scraper can be adjusted vertically or upwardly along the block or saddle 38 so as to bring the scraper to desired elevation.

The plow herein described is susceptible of a large number of adjustments and is designed to be used for a great variety of purposes. Importance is attached to the use of the open fork 2? whereby the king bolt at can be adjusted to the lower limit of the slot 3, thereby allowing the point to be used when worn down to the smallest possible size. The runner 26 can be provided with upwardly extending ears for pivotal en- 7 gageinent by a bar 23 whereby said runner can beadjusted angularly bymeans of any suitable mechanism provided for that purpose.

Bolts 85 and 36 serve to hold the saddle 38 in position as shown.

VJhat is claimed is In a plow the combination with a stock of an angula'rly adjustable runner having a forked end straddling and pivotally connected to the stock, an upwardly pro ecting portion on the runner between the ends thereof, there being a series of transverse teeth upon the front face of the upwardly projecting portion, said series extending downwardly into the forked portion of the runner, a toothed member adjustably mount ed on thetoothed face of said upwardly projected portion, and a sweep secured to and extending across the front of the toothed member and back of the stock.

In testimony that I claim the foregoing as my own, 1 have hereto aflixed my s1g-- nature.
